52 * Zet working at 25 Mhz without any visible problems...
* Implemented a simple PIC and Timer to receive both IRQ0 and IRQ1
* Hard disk implementation:
* Compact Flash controller through sysace (thanks to Sébastien
Bourdeauducq)
* int13_harddisk() function with read/write support

49 New directory structure. root 5541d 21h /zet86/trunk/impl
48 Cursor shape in text mode implemented.
Also function 01 of int 10 (biosfn_set_cursor_shape)		 zeus 5546d 12h /trunk/impl
47 Implemented partial BIOS service int 1a (function 0), in order to prevent FreeDOS from doing weird things after a while.

With this bug corrected, there are no open bugs.		 zeus 5547d 07h /trunk/impl
46 int13 speedup (now it boots 50% faster) zeus 5548d 15h /trunk/impl
45 Major flaws corrected:

* BIOS pusha 8086 transformation correction
* Decoder corrected for: CMP, ADD, ADC, SUB, SBB, XOR, AND, OR with i
* Implemented functions 08, 09 and 0a of int 10h
* Keyboard BIOS interrupts int 16h and int 09h now working
